SPECIFICATION forming part of Letters Patent No. 372,885, dated November 8, 1887.

Application filed December 6, 1886. Serial No. 220,787. (No model.)

To all whom it may concern:

Be itknown that we, HARRY WIARD,JAMES- L. JUDD, and WILLIAM R. BULLooK, all of Syracuse, Onondaga county, State of New York, have invented certain new and useful Improvements in the Construction of Ditching or Road Scrapers, of which the following is a specification.

The purpose of our improvedimplement is m to form the several parts in a manner to give greater strength and durability, as well as lightness and facility of adjustment and efficiency in action, than has heretofore been attained. I 5 The following description refers to the drawings, in which- Figure l'is a top plan of the implement. Fig. 2 is a sectional elevation with one handle removed; Fig. 3, detail of the pivoting-segments and .the connections; Fig. 4, plan of the pivoting-plate of the pole and hounds, showing their connections.

We are aware that numerous devices have been employed for giving a desired position and action to scrapers with poles for various purposes; but they have all, so far as we know, lacked precision in adjustment, facility and ease in handling, and strength and durability in their construction that is the object 0 of our present device.

The frame of the scraper consists of the following parts: The side pieces, a a, are each formed of a single continuous'bar of metal, a,

united by a rod, b, on which, near its ends, are 5 collars b, that determine the distance of the bars a a apart. In front of rod b the side pieces, a a, of the frame are bent at an angle (see Fig. l) and form pole-braces, or hounds. At their forward'approximating ends they are 40 bolted to the wings c of a casting, c, that forms the pivoting center of the pole, through which a bolt, d, passes to unite them. This casting is composed of a disk, 0, above which are the wings c, uniting in a hub that forms the pivoting center. A collar or boss, 0 projects upward fronrthe hub at its center and fits intoasocketin a plate, f, aflixed to the pole that turns on it, the wear and strain upon the bolt dthat passes through them being relieved by this coupling.

In rear of the casting c a curved bar, g, is bolted to the hounds, with its broadest sec- 'tion vertical, as seen in Figs. 1, 2, and on this bar 9 the rear end of the pole p rests,anotched plate, 6, being interposed betweeen them and affixed to the pole, so as to slide laterally on the edge of the bar 9. Ahook-piece, e, embraces the under edge of bar g directly under the plate 6, and is made to clamp the pole securely to bar 9 at any point, from one side to the other, by which means the pole can be moved from side to side and adjusted indefinitely withthesmallest variation desired a matter of great practical importance in setting the machine to run properly in the varied work to which itis subjected.

In the rear of rod b the side bars, a a, curve upward and backward, forming the handles, so shaped at their rear ends as to fit the hands of the operator.

The scraper i is formed of a plate of metal bent into the form of the segment of a cylinder, as indicated in'the several figures, and is securely affixed on its convex side to two segmental castings, 8, located at the handles of the frame. These segments sare pivoted at their centers upon the ends of rod b, that project through the side bars, a a, of the frame far enough for that purpose. The peripheries of these segment-castings s are notched or toothed, as seen in Figs. 2, 3, the upper tooth being projected beyond the others to form a stop when the scraper has reached its extreme working position, as in Fig. 2.

Just in rear of the segments 8 pawls It are placed, pivoted to the side bars, a. These pawls are bell-cranked in shape, and are connected with a short hand-lever, Z, bya rod, k, which hand-lever is pivoted on the bar a in a position to be readily grasped by the hand on 0 the handle of the frame, by which the pawls k are detached from the notches in the segments s, and the scraper is freed and falls over into the position seen in Fig. 3. To bring the scraper again into action the handles a, are raised, lifting the scraper, which then swings into position, and the pawls k, being freed, by

their gravity, aided by a spring, if necessary,

catch into the proper notch in the segment and hold the scraper ready for Work. 10o

To assist the scraper in its work we employ a foot-board, m, placed in rear of the scraper, which is suspended by hooks t to the rod b, with its front edge resting against the scraper z. (See Fig. 2.) By stepping upon this foot-board the operator aids by his weight the action of the scraper, and relieves the segments and pawls of a considerable part of the strain upon them, as well as the scraper, and forces it into action.

In working this implement it is set to the proper pitch for the work to be done and the material to be handled, and the pole is set either at right angles to the scraper or in an inclined position horizontally thereto, the adjustment being varied for different soils and for different purposes with great accuracy, to cause the scraper to run properly. \Vhen the pole is firmly fastened to bar g by the clamp upon the end of the pole, the scraper is ready for action.

Having thus fully described our improvements in the construction of scrapers, we claim 1. The coupling-hook c and pivoting-joint 2 c, in combination with the curved bar 9, for holding the scraper at the proper angle to the pole, constructed and arranged as and for the purposes specified.

2. The side bars of the frame, each formed 30 HARRY VVIARD. JAMES L. JUDD. WILLIAM R. BULLOCK.
